Currently the Mediation server only support DTMF outband (RFC 2833). Some sip trunk providers supports inband as well as outband. If the caller is sending DTMF inband only, the Mediation server will not recognize it.

More and more PBX systems are no longer playing ringback sound. This is currently generating the Skype for Business Client. If now the user with the sound options all tones deactivated it does not receive ringback or busy tone. It would be good if you can import the audio file centrally on the SfB server.

The time threshold for a call queue to time out needs to be less than 1 minutes. 1 minute waiting on a call if no one answers is a VERY long time before a new workflow starts. This should be seconds, not minutes.

We have several clients in northern Wisconsin that are interested in moving to CloudPBX. As we are working with one customer, Microsoft notified us that Bandwidth.com does not have agreements in some areas of northern Wisconsin. Can anyone tell me what we need to do to get this area of the US coverage? This is holding up a number of sales for us.

Would be nice if you provided any support for your enterprise PSTN and Cloud PBX systems. I cannot get any information or timeline to why my enterprise phone system is completely down. How can you sell a product and have zero escalation support? Your website has the general Office365 support contact, and they do not have any visibility into the phone systems at all.

The functionality is similar but there are several disparate items between UMO and Azure VM. Enterprise-class accounts, like E5, should not be relegated to AzureVM. A big concern is RMS and Protected Voicemail to prevent voicemails from being saved or forwarded. Refer to https://technet.microsoft.com/en-us/library/dd351041(v=exchg.150).aspx for information.

The cause is that Azure VM uses EWS to write the notification and mp3 into the recipient's inbox, where UMO writes it into a container and then an SMTP agent routes the notification through Transport, where RMS is leveraged to apply IRM to the notifications.

Right now we can access our voicemail messages using our Skype enabled Polycom phones but we cannot access any options in the voicemail system. Currently the only option is to press 1 to listen to messages and 0 to repeat that same Prompt. We would like to be able to change our voicemail greetings or set out of office messages using the phone itself. There should be an option 2 to change greetings available.
